This repository contains libraries for working with special relativity, implemented in Python, Rust and C#. It also contains some Jupyter notebooks demonstrating their use.

This section contains Jupyter notebooks, and a shared Python library. A great place to start.

These libraries are compiled and higher performance than the Python tools. Two projects are included:
https://github.com/lookbusy1344/Relativity/tree/main/rust_uom
Strongly typed and units of measure tools. These are based on f64 (double precision floats) and so are not as accurate as the Python tools.
https://github.com/lookbusy1344/Relativity/tree/main/rust_astrofloat
Alternative Rust tools using the astrofloat crate for arbitrary precision calculations. However the astrofloat hyperbolic trig functions are not as accurate as the Python mpmath functions.

This project contains both a strongly typed units of measure library (equivalent to the rust_uom library) and a library for arbitrary precision calculations (equivalent to the Python library or rust_astrofloat).
